,DOG RACE TRACK.

Application llecl June 1,

rl`his invention relates to dog racing devices, and particularly tocertain improvements upon the dog racing device shown in our pendingapplication for patent, Serial. No. 171,304, filed on the 26th day ofFebruary, 1927.

One of the objects of the present invention is to provide means wherebythe rabbit at any desired part of the course may be caused to leap intothe air as if jumping a hurdle. I

A further object is to provide' a spring suspension for the motor of therabbit carriage.

A still furtherobject is to provide wheels disposed to bear against eachside of the track so as to prevent any lateral movement of the carriage.

Other objects will appear in the course of the following description.

Our invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a transverse section of a dog race track showing one of thesupporting posts in elevation;

Figure 2 is a side elevation of a portion' of the track and carriageoperating thereon;

Figure 3 is a vertical sectional view showing the carriage in elevationor looking toward one end thereof.

Referring to these drawings, 10 designates a wooden track which, ofcourse, has any desired extent and may be a straightaway track or acurved track, as desired. This track is supported by means of thc I-beam11 which is bolted to the bracket l2 which projects outward from anysuitable pole or support or any other overhead structure. XVe do notwish to be limited to the particular construction of the track. lVe haveshown the I-beam as being formed ot two channel irons to permit thepassage of electric wires but, of course, are not limited to this. Thetrack 10 carries upon its upper face the wear plates 13.

The carriage upon which the rabbit is supported includes the motorsupporting frame 14. The forward end of this frame has a forwardlyprojecting lug 15 and a two-armed yoke 16` is pivotally engaged withthis lug 15, the two arms 16 extending upward and inward around thetrack l() and carrying upon their extremities the wheels 17 which bearupon the wear plates 13. The rear end of the motor supporting frame 14is also formed with a rearwardly `pro- 1927. serial No. 195,779.

jecting lug or lugs '18 having the yoke arms 19 operatively engagedtherewith, which extends upward and then inward over the track and carrythe wheels 2() which also rest upon the wear plates 13. The lower end ofthe yoke 19 is formed with a downwardly depending pin 2l which extendsthrough an aperture in the lug 18 and the lug 18 rests upon a coiledcompression spring 22 which surrounds the rod 21 and at its lower endbears against a nut 23 carried by this rod. Thus one end of the motorframe is spring-supported, thusac- -commodating irregularities in thetrack.

Mounted upon the motor shaft 24 are the relatively large dished wheels25 car'rying preferably the rubber tires 26 which bear against the underface of the track 10, these wheels constituting means whereby thecarriagemay be driven. The spring 22, it will be seen, urges thesewheels upward against the under face of the track soas to secure a goodtractive engagement therewith. Also mounted upon the frame of the motoror upon the yokes 16 are arms 27 which carry upon them the rubber-tiredwheels 28 which bear against the opposite faces of the vertical web ofthe I-beam 11. These arms 27 may be mounted in any suitable manneras,for instance, in the manner illustrated in our prior application, but itwill be noted that in the prior application these arms carried rollersof relatively small diameter, whereas the wheels 28 are of relativelylarge diameter. These wheels 28 prevent the motor and its supportingframe or yoke from any tendency to twist upon the track and cause thecarriage to take. all the curves of the track. j

The rabbit 29 is mounted 0n the end of a depending arm 30. The upper endof this arm is carried upon a transverse rock shaft 31 mounted insuitable bearings, in the yoke arms 16, the arm supporting the rabbitextending downward and forward, though it will be understood that therabbit-supporting arm might trail behind the carriage, assuming that thecarriage is moving in a reverse direction to that illustrated 1n Figure2. The shaft 3l carries an upwardly and rearwardly projecting arm 32having a roller 33 or lwheel at its upper end. At intervals along thetrack or at any desired place iro.

:tace of the track 10, but when the roller reaches this protuberanee,the rear end of thearm 32 will be depressed and the rabbit will havelifted so that the rabbit can under these circumstances pass over ahurdle or other obstruction on the track, thus causing the do s to jumpthe hurdle when they reach it. T ere may be as many of theseprotuberances 34C as desired.

For the purpose of lighting the track, we have provided the upwardlyextending tubular post 35 embedded at its lower end in concrete andhaving the brace 36 which extends upward to the lateral arm 37 of thepost. This. post is hollow, as is the arm. llhe ll-beam 11 is attachedto the extremity of the arm by bolts or other suitable means and thewires 38 which lead :from any suitable source of energy pass throughthese hollow posts 35 and are then carried to the metallic plates 14which engage the metallic trolley wheels 17. From thence the currentpasses by wire to the motor in the manner illustrated in our priorapplication. We do not wish to be limited to any particular means forconducting the electric current to the motor, as this may beaccomplished in any obvious manner. 'llhe current might be taken, forinstance, from the wheels 28 or from the wheels 17 or the wheels 20, asdesired. Electriclights 39 may also be mounted upon the braces 36 andconnected to a source of current so as-to illuminate the track.

While we donot wish to be limited to this, preferably the post 35 willbe formed in two sections, a short section which is inserted in aconcrete base and a longer upper section, these sections to be connectedb'y a screw-threaded coupling 40' so that if it be desired to shift thetrack from one place to another, the upper sections of the post 35 maybe removed from the lower sections without the necessity of tearing upthe concrete bases or constructing new posts.

1. A dog racing apparatus including an overhead track, a carriageoperating on the track, a motor mounted on the carriage, means forconducting electricity to` the motor, a lure support pivotally mountedupon the carriage and normally extending downward therefrom, the luresupport having an arm, and a roller engaging the under face of thetrack, the under face of the track being provided at intervals withprotuberant portions acting to depress the roller and elevate thelure-supporting arm.

2. A dog racing apparatus'including an overhead track, a carriagedisposed below the track, a motor mounted upon thencarriage and disposedbelow the track, hangers engaged with one end of the carriage andextending upward, trolley wheels carried by said hangers and bearingagainst the track,

trolley wheels disposed in advance of the carriage and having membersextending downward therefrom, a stem extending downward from saidhangers and extending through the carriage, and a spring engaged at oneend with said lstem and at the other end with the carriage whereby tocause the weight of the carriage to yieldingly urge the forwardtrolleylwheels downward against the track, and a lure depending from thecarriage.
